We are extremely pleased with the work done. The technicians were great! They worked nonstop, in rain that alternated between drizzle & pouring AND it was very windy. They were courteous & professional, did an excellent job, and an excellent clean up before they left. Great work! Amazing looking results! Not ten stars..more like 20 stars!! Thanks!

We had been going back and forth on trying to remove asbestos and do the abatement ourselves. I can. It say how impressed we are with Certified. They were very detailed in the bid and process. Explained every step they did and why. It was worth every penny for them to do our 700 sqf of space. Thank you very…
